I guess when I am confronted with a serious sin, such as murder, rape, extreme cruelty, torture, terrorism, and any number of sins I have never been tempted to commit, by witness or report, I momentarily hate such sins more than my own (while not for a second denying my own sinfulness, unworthiness, or complete need for God’s mercy) because of my empathy for the victims of such sins.
However, I also feel tremendous pity for the sinners and usually feel compelled to pray for them, reminding myself that there but by the grace of God go I,
I also frequently pray for the forgiveness of those who have hurt me, remembering that I will be forgiven in the same way that I have forgiven.
In another sense, I hate all sin equally because sin impedes the soul’s progress to God. In this sense I never hate anyone else’s sin more than my own.
I never hate sinners when hating sin. That qualification is important. I desire heaven for myself and everyone else. I do this because I desire God’s mercy and cannot ask it for myself if I wish that it be denied to others. I also do it because I see the same human weakness from with which I struggle in all people. This moves me to love others and have compassion on them, no matter how sinful they are, and greatly desire their salvation.
